About the appliance compute node disk drive
configurations
The NetBackup 5340 Appliance compute node contains five 2 TB SAS hard disk
drives, which can be accessed from the compute node's front panel. An embedded
RAID controller on the compute node's mainboard is used to configure four of the
five disk drives into two RAID1 mirrored volumes.
The two RAID1 volumes are labeled Volume 0 and Volume 1. The disk drives that
are located in slot 0 and slot 1 are configured as the RAID1, VOLUME0 device.
These disk drives contain the appliance operating system, the operating system
swap file, and the NetBackup application. You can hot-swap one of these disk drives
at a time if a drive becomes problematic. However, you cannot operate the appliance
if both disk drives are removed.
The disk drives in slot 2 and slot 3 are configured as the RAID1, VOLUME1 device.
Volume 1 contains the log files. As with the RAID1, VOLUME0 device, you can
hot-swap one disk drive at a time if a drive becomes problematic. However, you
cannot operate the appliance if both drives are removed.
The appliance uses the disk drive that is located in slot 4 as a hot-spare disk. If a
disk drive in either of the RAID volume experiences a hardware error, the appliance
automatically initiates a RAID rebuild operation. During the rebuild operation, the
appliance dynamically accesses the hot-spare disk from slot 4 and uses it to rebuild
the RAID volume.
